Restrictions of DEDB Unload

When a randomizer is invoked by IMS, Registers 10 and 11 contain the addresses of the EPST and ESCD, respectively. Some user-written or user-customized randomizers are designed to use these addresses to gain access to IMS control blocks other than those passed as part of the published interface. When one of the DEDB Unload/Reload utilities issues a call to a randomizing module, Registers 10 and 11 are set to -1 to 0, respectively, to specify that the call is not being issued in a "live" IMS environment.

DEDB Unload (FABCUR1) does not support Automatic RECON Loss Notification.
